Canon A4000 IS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Canon 5D has a
13.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic II processor.
Below you can see the A4000 IS and 5D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon A4000 IS and Canon 5D Cameras
As seen above, Canon 5D has a 30.8x Larger sensor area than Canon A4000 IS. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon A4000 IS
or the
Canon 5D ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus Full frame),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
